I've sent a video and pictures to Crutchfield. Will see what they say.
It's any light, but the more light.. the more visible they are... and it doesn't show at all when viewing at certain angles. One speaker only has it on one side. The other has it on the top, the back and one side. They sound great. They will be primarily in a dark room with shut blinds so I can probably live with them. My concern would be resale value if I ever want to upgrade or if I ever move and they need to sit in a well lit room.
I would think other people would have this issue if its a manufacture / assembly issue. Anyone else have the 8000fs with this?
